Improvements to the simmer code model for steel wall failure based on EAGLE-1 test results

Toyooka, Junichi  ; Kamiyama, Kenji  ; Tobita, Yoshiharu; Suzuki, Toru

In this paper, for the purpose establishing more generalized models for the SIMMER code to reproduce the effect of steel component on mixture-to-wall heat transfer in the EAGLE-1 program, the authors performed a model improvement for the SIMMER code to treat the direct contact of the molten steel in a more mechanistic manner. By this model improvement, evaluations with unifying agreement on a result of the EAGLE-1 program using the SIMMER code could be possible.
